Abstract
Abstract Alkyd-compatible second binder resins for use in traffic paint formulations are prepared from an alkylstyrene, an alkyl acrylate and butadiene by graft polymerization of alkylstyrene and alkyl acrylate onto a preformed alkyl styrene-butadiene substrate. The product resins, comprising 50% to 90% by weight of an alkyl styrene, 0.5 to 5% by weight of a conjugated diene and 29.5 to 10% by weight of an alkyl acrylate, are employed in reflectorized alkyd traffic paint formulations to provide enhanced compatibility with aliphatic solvents, rapid drying, good wear properties, and improved retention and reflectivity.
